hey y’all, I’m about 5 weeks into flower and for the last week and a half Iv been getting very strange brown spots on the plant.

At first, I noticed a lot of lower level fan leaves dropping; but I figured that was normal for entering flowering with lots of colas. However, now I’m getting these brown spots on top growth attached to my buds!! Iv already trimmed more than I’d like away trying to remove it.
At first I thought leaf sophoria, but it doesn’t seem to match up with the photos and symptoms I see.
I do know for sure that I hit her twice about 2-3 weeks ago with water that was too low ph (like 4.3) and that was a big watering, but I quickly corrected that within the week and runoff was back to 6.
Does it have to do with calcium? Iv been using cal mag about once every 2 weeks

Thanks for the help guys!! 60CCAA07-E8A4-4F7D-8267-B5573466C81F.jpeg9F1756C6-A4C0-450A-9957-D7F20E87B880.jpeg 7CF7CAD4-4E97-4844-BC81-8013BB54C68A.jpeg

It looks like p def. It could be from locking out, like you mentioned. If you feel it’s not, you could also check out fungus gnat damage.

agree with @frizfrazjaz on the P. Actually I think you just need to ramp up feeding. Those plants look a light/lime green which tells me they're not getting enough nutrients to begin with.

Right, which could be caused by nutrient lockout. Always a good idea to first make sure you pH is on point, and if so, raise the feeding PPM's.
